Amazingly strong. Compare that to the AS350 when the wire flicked into the main rotor (tail boom shook itself off).

Back in August 81, a RAAF B model Huey had a tail rotor problem which led to the gearbox tearing itself out, a mast bump and rotor separation, and a drop from 1500'. Not quite the same as ploughing a paddock, but the forces must have been similar. And it stayed on, and it kept flying. Those Russkies!

I don't want to split hairs, but this appears to be a Mil Mi-2, which was actually produced in Poland. And, Poland wasn't part of the Soviet Union, so it's not technically speaking a 'Russian' helicopter.
